PC Bug: Game Misinterprets Mouse Movement, Freezes Gameplay

Status:	Duplicate
Added by:	fallenknightzath on March 1, '26
Reported for:	9.4.2
Actual Result:	DBD Unfocusing, your mouse appearing, and the game becoming unfocused as if you've alt-tabbed.
Expected Result:	The mouse remaining locked to gameplay.
Severity:	Major
Reproducibility:	Sometimes
Platform:	Steam
Additional Notes & Comments:	This is an INCREDIBLY frustrating issue that has only occurred when playing Dead By Daylight. I have tried several suggested fixes, none of which have worked. My current belief is that this is caused by having two monitors with desynced refresh rates, but I cannot confirm.

Steps to Reproduce

1. Play Dead By Daylight, either in borderless window or in fullscreen.
2. Your mouse moves to the side of the screen while playing.
3. The game acts as if you have clicked off of DBD and you lose focus, even though your cursor has not left the screen.
4. You must click into the game to restore focus.

Explanation

There is currently a PC specific bug where you will sometimes randomly click off of the main screen and the game will act like you've clicked onto a second monitor.

This bug persists despite having the game be in fullscreen and using third party software to force the mouse to lock to the selected screen.

This causes an instant freeze and robs you of the ability to control your character, often resulting in a swift death as survivor or a missed hit as killer. This most often happens on killer as you move your mouse around quite constantly.
